12 Claims. (01. ill-62.6)

This invention relates to paint stripers.

It is an object of this invention to provide an improved paint striper which is relatively simple and inexpensive in construction and eflicient in use.

Another object of the present invention is to provide a paint striper in which there is a positive feed of paint or analogous striping material from the main storage magazine or reservoir to the work, regardless of the position in which the striper may be used, that is, regardless of whether the same is used vertically, horizontally, or at any angle between these positions.

Another object of the invention is to provide a novel striping wheel-holding unit which may be attached to a conventional storage receptacle or container, of standard design, such as an ordinary standard-sized bottle, and, when thus attached to such a conventional receptacle, for paint or analgo ogous striping material, will provide, with the latter, an eificient paint striper.

An additional object of the invention is to provide a paint striper which embodies means for positively and mechanically forcing paint or analogous striping material onto the striping wheel of the same when working overhead, that is, when the workman or operator is painting a stripe upon a surface or work which is overhead.

A further object of the invention is to construct the new paint striper in such a manner that the striping wheel-holding jaws embodied in the same, and the striping wheel carried thereby, may be removed and replaced by a difierent set or pair of jaws for a narrower or wider striping wheel, so that by providing a plurality of sets of jaws and striping wheels of various widths for assembly with the other parts of the same the new striper may be used for painting stripes of different widths and without providing a complete and separate striper for each striping operation and width of stripe.

Still another object of the invention is to provide, as a part of the same, a novel striping wheelholding unit or head in which there is provided an auxiliary storage reservoir for a relatively small amount of paint or analogous striping material so that, regardless of the position in which the striper is used, and the position of the main storage reservoir or container, there will always be a supply of paint in this auxiliary reservoir ready to be discharged therefrom onto the striping wheel as soon as the striping wheel is placed in rolling contact with the work or surface to be striped and is moved thereover to effect the striping.

Other objects of the present invention are: to provide a striping wheel-holding unit or head which carries a device for guiding the striper during the striping operation; to construct the striping wheel-holding unit or head in such a manner that the striping wheel-holding jaws embodied in thesame not only provide means for holding the striping wheel in position of use but also cooperate with each other to provide the auxiliary storage reservoir, hereinbefore referred to. and which reservoir provides a passage, for paint or analogous material, between the main reservoir or receptacle and the striping wheel; to construct the striping wheel-holding head in such a manner that the jaws and the striping wheel embodied in the same may be removed from the clamping means or coupling by which the jaws and striping wheel are attached to the main receptacle so that a plurality of striping wheels of different widths, and corresponding pairs of jaws for holding the same, may be sold with the new striper and be readily attached to, and removed from, the main receptacle or container by the same clamping means or coupling, so as to paint stripes of varying or different widths; and to construct the striping wheel-holding head in such a manner that a plurality of storage containers or receptacles such, for example, as bottles, of standard size, filled with paint, lacquer, oils or other striping materials, may be kept on hand by the user of the new paint striper and readily attached to and removed from the said striping wheelholding head.

Another object of the present invention is to construct one form of the same in such a manner that a plurality of stripers may be mounted upon a single or common holder; and to construct this form of the invention in such amanner that the stripers or striping wheels themselves may be moved or adjusted independently of the handle of the device so that the same may be used in various places, such as in corners, where it would not be possible to use the striper if the striping wheels were disposed in their normal position and in which planes passed vertically through the same are parallel to the long axis of the handle.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:

Fig. 9 is a central vertical sectional view on line 99 in Fig. 8; and

Fig. 10 is a bottom plan view of the form of the invention which is shown in Figs. 8 and 9.

A typical embodiment of the new paint striper is shown in Figs. 1 to 5, inclusive, of the drawings, is therein generally indicated at I0 and comprises, in general a main receptacle or reservoir which has the form of a cylinder H which is adapted to hold paint, lacquer, oils, or other analogous striping materials; and a striping wheel-holding unit or head which is generally indicated at l2 and which is detachably attached to the main storage reservoir or receptacle II in a manner which will be described presently.

The main storage reservoir or receptacle II has an open outer end l3 and detachably attached to the said storage reservoir l l at this open outer end l3 of the same is a closure member or cap l4. Provided in this closure member or cap I4 is a central opening l5 and slidably projected through this opening I5 is a plunger or slide rod l6 which has a handle I! at one end and a piston l3, of conventional design, at its other end, this piston It! being slidably arranged in the main storage reservoir or cylinder II.

In the embodiment of the invention which is shown in Figs. 1 to 5, inclusive, the main storage reservoir or receptacle II is provided with a reduced neck portion I9 and this neck I9 is detachably attached-to the striping wheel-holding unit or head l2 by means of cooperating threads and 2| of standard size and design, the threads 20 being formed upon the external surface or periphery of the neck l9 and the threads 2| being formed upon a neckportion 22 of a combination clamping and coupling member which is generally indicated at 23 and which forms part of the striping wheel-holding unit or head l2.

The striping wheel-holding unit or head' l2, in addition to the combination clamping and coupling member 23, also includes a pair of complementary striping wheel-holding laws 24 each of which is provided, on its inner surface, with an axially extending bore or groove 25 (Fig. 5), and these two grooves 25 cooperate, when the laws 24 are in assembled position, that is, in position of use, to provide a passage 26 which functions as an auxiliary storage reservoir or magazine for paint, lacquer or other striping materials which, in the use of the device, are delivered thereto from the main storage reservoir or magazine II.

It will be noted, Figs. 2 and 3, that there is formed in the combination coupling and clamping member 23 a substantially frusto-conically shaped central passage or seat 21 and it will also be noted, by reference to Fig. 2, that when the two striping wheel-holding jaws 24 are in assembled and complementary position they form a generally frusto-conically shaped unit which is projected through, and seated in, the correspondingly shaped bore or seat 21 which is formed in the coupling and clamping member 23.

Each of the striping wheel-holding jaws 24 is provided, at its outer and smaller end, and at the end of the corresponding groove 25 which is formed therein, with a substantially circularshaped face or bearing surface 28 and provided in each jaw 24, centrally of the corresponding face or bearing surface 28, is a bearing opening 29 which is adapted to receive a corresponding end portion of the shaft 30 of a striping wheel 3! which is provided, for reasons to be explained presently, with a serrated peripheral edge or surface 32.

In the embodiment of the invention which is shown in Figs. 1 to 5, inclusive, the coupling and clamping member 23 is provided with a boss 33 and extending through this boss 33 is a cylindrical bore or passage 34 through which is extended one arm 35 of a guide member 38, this guide member 36 having an arm 31 which is provided, at its outer end, with an enlarged portion 38 which is adapted to engage an edge portion 39 of the work or surface over which the striper is being moved (Fig. 1) so as to guide the striper during the striping operation. This guide member 36 may be releasably clamped in any desired and preselected position, upon the coupling and clamping member 23, by means of a set screw 40 which is threaded into the boss 23.

Arranged in the coupling and clamping member 23, between the neck I9 of the main storage receptacle or reservoir II, and the auxiliary storage reservoir or passage 26, is a washer or gasket 4! which is provided with a central opening 42 and this opening 42 is considerably smaller in diameter than the bore or diameter of the auxiliary reservoir 26 or passage, for reasons to be explained hereinafter.

Operation of the device shown in Figs. 1 to 5, inclusive In the use of the embodiment of the new paint striper which is shown in Figs. 1 to 5, inclusive, the closure member or cap l4 and the pistonplunger l'|--l6 may be removed from the open end l3 of the main storage reservoir or receptacle ll so as to fill the latter with paint, lacquer or other analogous striping material.

The manner of assembling the parts of the striping wheel-holding unit or head l2 together is as follows: With the main storage receptacle or cylinder II and the striping wheel-holding unit or head ll separated or detached from each other, a striping wheel 30 of a suitable width and of a suitable diameter, is arranged between the bearing surfaces 28 of the clamping jaws 24 with the end portions of the shaft 30 of the same projecting into the corresponding openings 29 in the bearing surfaces 28 of the jaws 24. The two jaws 24, with the striping wheel 30 held therebetween, are then, while being manually held together and against displacement relative to each other, projected downwardly (Figs. 2 and 3) into the central opening in the clamping and coupling member 23 wherein they are seated in the frusto-conlcally shaped central opening or seat 21 which is formed in the latter. The apertured gasket 4 I, which functions as a check valve, is then arranged in the coupling and clamping member 23, upon the jaws 24, and the neck IQ of the main storage receptacle 43 or cylinder l is then screwed into the neck 22 of the coupling and clamping member 23, therebysecurely clamping the jaws 24 together and in complementary position, and the striping wheel 30 therebetween, in position of use, and against displacement therefrom. I

It will be noted that paint or other analogous striping material will then flow by gravity, (or may be forced by depressing the piston-plunger |6-|1), from the main storage reservoir 43 or cylinder I through the opening 42 in the gasket 4 I, into the auxiliary reservoir or passage 26, thus filling the latter and rendering the striper ready for use.

Accordingly, in order to use the embodiment of the new paint striper which is shown in Figs. 1 to 5, inclusive, the guide member 36 may be adjusted so that the long axis of the arm 31 of the same is parallel to the plane of the disc or striping wheel 3| and the enlarged end portion 36 of the arm 31 of the same bears against an edge or portion 39 of the work, whereupon the said guide member 36 may be clamped in the desired position by means of the set screw 40, and the striper will then be ready for use.

With the arm 31-48 of the guide member 36 bearing against an edge or other portion 39 of the work the serrated peripheral edge 32 of the striping wheel 3| is then placed in bearing engagement or contact with the work, or surface to be striped, and is moved along the latter over a the desired route. During this striping operation the serrated peripheral edge 32 of the striping wheel or disc 3| contacts with the paint or other analogous striping material which is disposed in the auxiliary reservoir or passage 26, and at the outer end of the latter, and positively feeds the paint or other striping material from the auxiliary reservoir 26 to the surface over which the striping wheel 3| is being moved. In this manner the paint or other analogous striping material is positively forced or fed from the auxiliary reservoir or passage 26 to the work, that is, to the surface over which the striping wheel 3| is being moved, and hence the present striper does not rely merely upon a gravity feed of the paint or other analogous material, as in the conventional prior art stripers, but employs a positive feed from the latter. This assures that the paint or other striping material will always be fed to the work or surface over which the striping wheel 3| is traveling, regardless of the position of the striper, that is, regardless of whether the striper is being employed for overhead work, and is being held in inverted position, or is being used in its normal and upright position (as in Fig. 1). It is also to be noted, in this connection, that this assurance .of a positive feed or supply of paint or other analogous striping material from the striper to the work or surface being striped is increased, in the embodiment of the invention which is shown in Figs. 1 to 5, inclusive, by the fact that the apertured gasket 4| acts as a check valve, that is,

when a supply of paint or other striping material has entered the auxiliary reservoir or passage 26, from the main reservoir or cylinder H or 43, it is prevented from flowing back into the latter by reason of the fact that the opening 42 in the gasket 4| is relatively much smaller in diameter than the neck IQ of the main reservoir II and the auxiliary reservoir or passage 26. Hence, the apertured gasket 4| acts as a check valve and prevents backfiow of the paint or other analogous striping material from the auxiliary reservoir or passage 26 into the main reservoir H, and this feature is especially important when the striper is being used in inverted or overhead p'osition, since it assures that in this latter case, especially, there will always be a supply of paint or other striping material in the auxiliary reservoir or passage 26, ready to be fed to the work by the striping wheel 3|. It may be observed at this point that any other conventional form of check valve may be substituted for the apertured gasstriper shown in Figs. 1 to 5, inclusive, is being used in inverted or overhead position paint, or other analogous striping material, may be positively forced from the main storage receptacle ll into the auxiliary reservoir 25, and from the latter to the striping wheel 3|, by depressing the plunger-piston I6|8, by means of the thumb, while grasping the body of the cylinder ll between the fingers and palm of the same hand.

It has been found that in the use of the new paint striper the serrated peripheral edge 32 of the striping wheel 30 is an important feature of the same since the serrations or notches in the striping wheel 3| act as a conveyor to feed or convey paint or other analogous striping material from the auxiliary reservoir or passage 26 to the work.

An important feature of the embodiment of the new striper, which is shown in Figs. 1 to 5, inclusive, is that the striping wheel-holding head l2 may be readily detached from the main cylinder or storage magazine II, and the wheelholding jaws 24 lifted or raised up out of the clamping and coupling member 23, so as to replace the said jaws by another pair or set of the same holding astriping wheel of a different width than that shown in the embodiment of the invention shown in Figs. 1 to 5, inclusive, and which is a relatively narrow striping wheel. It will be seen, therefore, that by providing and selling several or more sets of jaws 24 and corresponding striping wheels of different widths. with the new striper, stripes of various and different widths may be painted without requiring a separate and complete striper for each striping operation.

It is to be noted, in this connection, that the several pairs of jaws 24 which may be sold with the new striper are all constructed in the same way except that for a wider striping wheel than the particular wheel 3| which is shown in the embodiment of the invention illustrated in Figs. 1 to 5, inclusive, the space between the bearing surfaces 26 on the jaws 24 is increased so as to accommodate the wider striping wheel arranged therebetween. Otherwise the several sets or pairs of jaws are identical in construction and may be successively placed upon the same seat 21 in the coupling and clamping member 23, thereby eliminating the necessity for providing a separate coupling and clamping member 23, guide 38, and storage receptacle II, for each striping wheel and thus making it possible, by interchanging or replacing the jaws 24 and striping wheels 3|, to form stripes of various and difierent widths.

Modification shown in Fig. 7

A modified form of the invention is shown in Fig. 7, is therein generally indicated at 43, and comprises a main paint storage reservoir or cylinder 48 and a striping wheel-holding head or unit 44. This striping wheel-bearing head or unit 44 is identical in construction to the wheel-holding head or unit I 2 which is embodied in the form of the invention shown in Figs. 1 to 5, inclusive, and includes a coupling and clamping member 45, a striping wheel 32, and a guide 41, all of which are identical in construction and operation to the corresponding parts 23, 3|, and 35 respectively, which are embodied in the form of the invention shown in Figs. 1 to 5, inclusive.

It may be observed, at this point, however, that the difference between the embodiment of the new striper shown in Figs. 1 to 6, inclusive, and that shown in Fig. '7, resides in the fact that in the striper shown in Fig. '7 the main paint storage reservoir or cylinder 48 is a standard container of conventional design, that is, it is, in the embodiment of the invention shown, a standardsized bottle having a standard thread in its neck portion which may be threaded into corresponding threads which are formed in the coupling 45, just as the neck [9 of the cylinder II is screwed into the coupling 23 in the form of the invention which is shown in Figs. 1 to 6, inclusive. Otherwise, the striper which is shown in Fig. 7 is identical in construction and operation to the striper shown in Figs. 1 to 6,inclusive, and hence need not again be described in detail'here.

It is to be noted, in connection with the striper which is shown in Fig. 7, that the main paint storage reservoir or receptacle 48, being a bottle or other container of standard size and having a neck portion provided with standard threads, may

be readily purchased on the market, as, for example, in drug stores, hardware stores, department stores, and the like, and is very inexpensive, so that the user of the new striper may purchase a number of the containers or bottles 48 and keep the same on hand, filled with paint, lacquer, or other analogous striping material, ready to be screwed into, and attached to the striping wheelholding head 44 (or into the head l2) and it will be noted, in this connection, that both of these heads l2 and 44 are provided with threads of a standard size so as to receive a corresponding thread of standard size which is provided in the neck 43 of the container or bottle 48. Thus, for example, in the embodiment of the striper which is shown in Fig. '7 the bottle or container 48 may be an ordinary stock medicine bottle, of any desired size and capacity, and which may be ob tained in any drug store, and has a conventional thread on the neck 43 thereof, and the head 44 isprovided with corresponding threads to receive the neck 49 of the container or bottle 48.

It will also be noted (Fig. 6) that the lower portion I8 01' the auxiliary reservoir 25 is restricted relative to the main extent thereof, and of the same width as the striping wheel itself so as to direct paint from the reservoir 25 onto the peripheral surface of the striping wheel 32 and thus prevent leakage past the sides of the same.

It will further be noted that the new striper may be readily taken apart and cleaned, which is an important feature in a paint striper which has a tendency to become clogged with dried paint.

It has been found. both in the use of the forms of the new striper which is shown in Figs. 1 to 6, inclusive, and in the form of the invention which is shown in Fig. 7, that it is not necessary to provide a vent opening in the main storage reservoir or cylinder H, behind the piston l8, nor in the container or bottle 48 to equalize the air pressure on both sides of the paint, and this is probably due to the fact that the serrated striping wheels 3| and 32 act as conveyors to convey the paint or other analogous striping material from the auxiliary reservoir or passage IE to the work or surface over which the striper is moving, thus overcoming the tendency of atmospheric air pressure to-prevent the flow of the striping material from the auxiliary reservoir 28 to the work. It has also been found that the embodiment of the striper which is shown in Fig. 7 will work satisfactorily without a plunger-piston, such as is provided at Il1l8 in the embodiment of the invention shown in Figs. 1 to 6, inclusive, although for overhead striping the use of a plunger-piston is preferred;

Modification shown in Figs. 8, 9 and Another modified form of the invention is shown in Figs. 8, 9 and 10, is therein generally indicated at 58, and comprises a plurality of striping units 5|, each of which includes a striping wheel 52, corresponding to the striping wheels 3| and 32, and a pair of wheel-holding jaws 53, corresponding to the wheel-holding jaws 24.

The striper I2 includes a holder, generally indicated at 54, and consisting of a socket member 55 in which are formed a plurality of sockets 56 for the reception of the striping units 5|, that is, each socket 56 is designed to receive a corresponding pair of the striping wheel-holding jaws 53 and the latter, and the striping wheels 52 held thereby, are arranged (Fig. 10) in the form of an isosceles triangle, although they may, of course, be arranged in any desired position or pattern relative to each other; the three striping wheel units 5I-52 being designated A, B and "C, for the purpose of identification in the description hereinafter set forth.

The holder 54 also includes an intermediate plate or disc 55a, which is keyed to the socket member 55, as at 51, (Fig. 9), and thisdisc 56a is arranged within a recess or seat 58 which is formed in the socket member 55. The holder 54 also includes an externally threaded top plate 53, which, as will be described hereinafter, provides a support for the paint storage reservoirs. Threaded onto this support 59 is a coupling ring 80, and this coupling ring 60 has, at its lower end, an inwardly extending annular flange M which engages under a complementary and correspondingly shaped annular flange 62 which is formed on the socket member 55, at the top of the latter.

Provided in the top plate 59, and preferably but, of course, not necessarily, formed integrally therewith, is a handle 83, and arranged between the parts 5811-53 is a felt or like gasket or washer 84, and another washer or gasket 85 is arranged between the socket member 55 and the disc 580.

Also provided in the top plate 59 or holder for the paint storage reservoirs, and preferably, but not necessarily, integral therewith, is an upwardly extending boss 66, and provided in this boss 66 are two spaced recesses or sockets 61 for the reception of the neck portions 68 of bottles or analogous paint-holding reservoirs 69, which may be similar to the bottle 48 and the outflow of paint from these bottles 69 is controlled by manually operated valves 18 which are adjustably mounted in the boss 66.

The boss 66 has a lateral and forwardly extending portion 10 and mounted on this portion 10 is a guide H, which corresponds to the guide 36-47, and is held on the portion 10 by means of a set screw 12, corresponding to the set screw 40.

Formed in the upper surface of the intermediate plate or disc 56a is an annular groove I3,

and also formed in, and leading through, the intermediate plate or disc 56a, from the annular groove 13 to the upper end of the striping unit 51-52-53 which is designated A (Figs. 9 and 10) is a passage 74. Leading from the lower end of the socket 61 for the paint reservoir 69 which is disposed in position C, through the top plate 59, to the annular groove 13 is a passage l and leading from the lower end of the socket 61 for the paint reservoir which is disposed in position B, through the top plate 59, is a passage 76, while formed in the intermediate plate or disc 56a, and extending from the annular groove 13 to the striping units B" and C are two passages 11.

In the use of the modified form of the inventionwhich is shown in Figs. 8, 9 and 10, the striping units A, B" and C are arranged in their respective sockets 56 in the socket member 55, whereupon the washer 65, (which is provided with apertures corresponding to the passages 14 and 11), the intermediate plate 56a, and washer 64, (which is provided with an aperture corresponding to the passage 15), are laid thereover, and these parts are then coupled to the top plate or handle-bearing member 59 by means of the threaded coupling ring 60. The neck portions 68 of the paint reservoirs or bottles 69 may then be inserted, in inverted position, into their respective sockets 61, and the valves 18 opened, whereupon paint will flow as follows: From the reservoir 69, which is disposed in position C, down through the passage I5, into the annular groove 13, and thence by way of the passages 11 to the striping units B and C while, at the same time, paint will flow from the other reservoir or bottle 69, through the passages 16 and 14, to the other striping unit A, thus enabling the user of the device shown in Figs. 8, 9 and to do two-color striping, if desired, by reason of the fact that the reservoir 69 which is disposed in position C may be utilized for supplying paint of one color to'the two striping units B and C whereas the reservoir 69 which is disposed in position A may be utilized for supplying paint of another color to the striping unit "A.

It will be noted, in connection with the form of the invention which is shown in Figs. 8, 9 and 10, that the striping wheel holder or socket member 55 and the intermediate plate 56a, which is keyed thereto at 51, may be moved or adjusted together as a unit and independently of the top plate or handle-bearing member 59, by loosening the coupling ring 60, thus making it possible for the user of the device to change the positions of the striping wheels 52 (together as a unit) relative to the handle 63, that is, by turning the socket member 55 and plate 56a, relative to the top plate 59, the vertical axes of the parallel striping wheels 52 may be varied so that the striping wheels 52 will all extend at an angle relative to the axis of the normally horizontal portion of the handle 63, instead of being positioned as shown, namely, with planes passed vertically through the striping wheels 52 being parallel to the normally horizontal portion of the handle 63, as shown, thus making it possible to use this form of the striper in places, such as corners and the like, Where it could not otherwise be used if the parts were arranged in a fixed position.

While I have illustrated and described the preferred forms of construction for carrying my invention into effect, these are capable of variation and modification, without departing from the spirit of the invention, I, therefore, do not wish to be limited to the precise details of constructions set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
